His, therefore, to be understood that the cylinder 8 has endwise movement with respect to the piston 10 and for this purpose the periphery of the cylinder 8 is provided therealong with a spiral groove or channel 14 into which is received the inner free end portion of the finger 6. The groove or channel 14 is disposed on any preferred degree of pitch but preferably at approximately ninety degrees although we do not wish to be understood as limiting ourselves in this respect.

The periphery of the cylinder 8 is also provided with a second spiral groove or channel 15 disposed on any preferred degree of pitch but less than the degree of the groove or channel 14, and it is to be further noted that the grooves or channels 14 and 15 are reversely disposed. The groove 15 receives the inner end portion of an inwardly directed finger 16 carried by the ring 2, said finger being also herein disclosed as a screw member threaded through said ring 2.

In View of this particular assembly it is believed to be obvious that as the seat S is raised the action of the finger 6 within the groove 14 will cause the cylinder 8 to move outwardly with respect to the piston 10 and which movement is facilitated by the fact that undue rotation of the cylinder 8 is prevented by the finger 16 which is received within the groove or channel 15. As the cylinder 8 moves outwardly air will enter therein through the port 18 disposed through the head 9, retrograde flow through such port 18 being prevented by the check valve 19. The tubular pintle 1 is provided with a suitable opening 20 to assure the requisite air supply. If preferred more than one of such openings 20 may be provided.

When the seat S is moved to return to mounted position upon the bowl B and after it passes the vertical, said seat S will continue its downward movement by gravity. but such movement will be checked or retarded by the compressing of the air within the cylinder 8 in advance of the piston 10. .This air, however, escapes through a vent opening 21 provided in the head 9 of the cylinder 8. The flow through said vent opening is regulated or controlled by the valve screw 22 of a conventional type. As is believed to be clearly apparent the greater the open area, of the vent 21 the quicker the seat S will drop and vice versa.

Each end of the tubular pintle 1 is preferably closed by a cap 23 threaded or otherwise secured thereon. V

The opposite end portions of the cylinder 8 carry the surrounding anti-friction assemblies 24 for coaction with the interior wall of the pintle 1 whereby the cylinder 8 has its desired endwise movement with a minimum of frictional resistance while at the same time these antifriction assemblies 24 serve to maintain the cylinder 8 in efiective working position.

To further assure the effective functioning of our combined hinge and check a coil spring 25 of desired tension is positioned between the inner end of the cylinder 8 and the mounting 12 for the rod 11. This spring 25 serves to resist the inward movement of the cylinder 8 and thereby further retard the closing movement of the seat S.

The tubular pintle 1 is non-rotative within the ring 2 and to assure this assembly of the pintle 1 and ring 2 there is threaded through the ring 2, as particularly illustrated in Figure 4, a binding screw 26 which has holding engagement with the pintle 1.

While we particularly illustrate and describe our combined hinge and check used in connection with a toilet seat and bowl it is to be understood that it can be employed to equal advantage in connection with other relatively movable parts.

From the foregoing description it is thought to be obvious that a combined hinge and check constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.

1. A combined hinge and check comprising two members, a tubular pintle disposed through said members for connecting the same for relative swinging movement, a. cylinder within the pintle having movement along the pintle, a stationary piston within the pintle and positioned within the cylinder, coacting means carried by the swinging member and the cylinder for endwise moving the cylinder upon swinging movement of said member, the second member having means coacting with the cylinder to hold the same against such rotation which would interfere with its desired endwise movement, saidcylinder having an inlet port, and a check valve to close said port against outward flow therethrough, said cylinder being provided with a vent.

2. A combined hinge and check comprising two hinge sections, a tubular pintle operatively connecting said sections, a cylinder positioned within the pintle for endwise movement, a stationary piston within the pintle and positioned within the cylinder, a spiral channel in the periphery of the cylinder, at part carried by one of the hinge sections extending within said channel whereby the cylinder is moved endwise upon swinging movement of said hinge section, said cylinder having an inlet port, and a check valve toclose said port against outward flow therethrough, said cylinder being provided with a vent.

3. A combined hinge and check comprising two hinge sections, a tubular pintle operatively conmeeting said sections, a cylinder positioned within the tubular pintle for endwise movement, a stationary piston within the pintle and positioned within the cylinder, a spiral channel in the periphery of the cylinder, a part carried by one of the hinge sections extending within said channel whereby the cylinder is moved endwise upon swinging movement of said hinge section, coacting means carried by the second hinge section and the cylinder to hold the cylinder against such rotation which would interfere with its endwise movement, said cylinder having an inlet port, and a check valve to close said port against outward flow therethrough, said cylinder being provided with a vent.

4. A combined hinge and check comprising two hinge sections, a tubular pintle operatively connecting said sections, a cylinder positioned within the tubular pintle for endwise movement, said cylinder having spiral channels reversely disposed, a part carried by one of the hinge sections extending within one of the channels whereby the cylinder is moved endwise upon swinging movement of said hinge section, a part carried by the second hinge section extending within the second channel to hold the cylinder against substantial rotation upon swinging movement of the first named section.

5. A combined hinge and check comprising two hinge sections, a tubular pintle operativelyconnecting said sections, a cylinder positioned within the tubular pintle for endwise movement, said cylinder having spiral channels reversely disposed, a part carried by one of the hinge sections extending within one of the channels whereby the cylinder is moved endwise upon swinging movement of said hinge section, a part carried by the second hinge section extending within the second channel to hold the cylinder against substantial rotation upon swinging movement of the first named section, the second channel having its pitch on a degree less than the degree of the pitch of the first channel.
